CHARLES ABRAHAM, 0F RICHFIELD, NEW JERSEY.

HOTBED.

To all whom "it may concern:

Be it known that I, CHARLES ABRAHAM, acitizen of the United States, residing in Richfield, Passaic county, and State of New Jersey, have invented certain new and useful Improvements in Hotbeds; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to letters of reference marked thereon, which form a part of this specification.

My invention consists in certain improvements in hot-beds having for their principal objects to facilitate the assembling and disassembling of the parts thereof, make it possible to vary the size of the hot-bed, and render the construction simple and durable in character.

The invention will be found fully illustrated in the accompanying drawing, wherein,

Figure 1 is an isometric View of the improved hot-bed; Fig. 2 shows fragments of two adjoining planks or boards forming the sides of the hot-bed; Fig. 8 shows said boards assembled with their supporting means, said figure being an inside elevation; Fig. i is a plan showing what appears in Fig. 3; Fig. 5 is a vertical sectional view taken to the left of one of the stakes forming a part of said supporting means; Figs. 6, 7 and S are perspective views of parts of one of said supporting means; and, Fig. 9 is a view of a modified form of one of the stakes.

In the accompanying drawings, a designates planks or boards forming the sides of the hot-bed. According to its length, each of said boards has one or more holes I) penetrating the same and where it is to abut end to end with another similar board it will have a notch c which, with a similar notch in the adjoining board, will form a hole substantially like hole 6 when the two boards are assembled as shown in Fig. 2. C

To supportthe several boards or planks I provide the following means: Stakes (Z are provided each having a horizontal seat or step e a distance from its upper end approXi mately equal to the depth of the boards to be supported. In the preferred form, said stake is formed of sheet metal, two reverse bends being produced therein (Fig. 5) so as Specification of Letters Patent.

to afford the seat 6. In the modified form shown in Fig. 9, where the stake f is of wood, the seat or rest 9 is produced by notching the upper end of the stake on the inside. Above the seat the stake is provided with an aperture 72., Fig. 5 (2', Fig. 9) through this aperture is passed a bolt j whose head 70 bears against the outer face of the stake. The inner end of the bolt is formed with a vertical opening Z adapted to receive the wedge m.

The parts of the hot-bed are assembled as follows: The stakes being driven into the ground in the proper disposition, their rests or seats facing inwardly, the boards or sides a are assembled therewith so that the holes I) and c of said boards will receive the bolts which are then entered through the holes h of the stakes. The wedges m are then driven into the holes Z of the bolts to bind the sides a securely against the stakes. Where the joints come between the abutting ends of two adjoining boards a each such joint is overlapped by one of the stakes; the stakes used at the joints are therefore preferably made wider, as shown, than the other stakes. In addition, a plate a is disposed at the inside of the joint to take the pressure of the wedge m, the said plate being apert-ured for the bolt, as shown. The seats or rests in the stakes, on which the sides rest, serve to insure the top edges of the boards forming said sides being level or alined with each other, it being understood that the stakes are driven into the ground until said seats are level with the surface of the ground.

Inasmuch as the innenends of the bolts constitute projections from the stakes serving to receive the wedges m it will be understood that I do not wish to be limited to such projections being removable from the stakes. In other respects, I do not wish to be limited to the precise construction shown and described, what I claim being:

1. In combination, with a side forming member of a hot bed and a stake member having a seat or rest, one of said members having a projection horizontally penetrat ing and protruding from the other and formed in its protruding portion with an opening, and a wedge entered into said opening and securing said members together, said side-forming member overlying the seat of the stake member, substantially as described,

2. In combination, with two adjoining side-forming members of a hot-bed abutting end to end, a stake disposed opposite the joint between said members and on one side thereof, a plate disposed opposite said joint on the other side thereof, said stake having a projection penetrating said members and the plate and protruding from the latter, and a wedge penetrating the protruding portion of said projection and securing said members, the plate and stake together, substantially as described.

3. In combination, with two adjoining sides of a hot bed abutting end to end, a stake member disposed opposite the joint between said sides and on one side of said joint, a plate member disposed opposite said joint upon the other side thereof, one of said members having a projection penetrating said sides at the joint and also the other member and protruding from the latter, and a wedge penetrating the protruding portion of said projection and securing said members and sides together, substantially as described.

In testimony, that I claim the foregoing, I have hereunto set my hand this first day of December, 1910.
